Изобретение относитс  к способу изготовлени  синтетической бума.ги из растворимых полив«нилспирт0вых волокон и может быть применено в бум1ажной промышленности при изготовлении новых видов бумаги.The invention relates to a method for producing synthetic paper from soluble watering of non-alcohol fibers and can be applied in the paper industry in the manufacture of new types of paper.

Известен способ изготовлени  бумаги из растворимых поливинилспиртовых волокон, включающий диспергирование волокон в воде, отлив полотна и сушку.A known method of making paper from soluble polyvinyl alcohol fibers, including dispersing the fibers in water, casting the fabric and drying.

Однако бумага, изготовленна  таким способом , не обладает достаточной механической прочностью.However, paper made in this way does not have sufficient mechanical strength.

Цель предлагаемого изобретени  - повышение механической прочности бумаги. Это достигаетс  тем, что бумажное полотно предварительно высушивают до 15-20% содержани  воды при 30-40°С, затем при 80-100°С досушивают бумагу окончательно.The purpose of the present invention is to increase the mechanical strength of the paper. This is achieved by pre-drying the paper web to 15-20% water content at 30-40 ° C, then finally drying the paper at 80-100 ° C.

Поливинилспиртовые волокна с метрическим номером 6000, раствор ющиес  в воде при 60°С, нарезаютс  длиной 1-3 мм, суспендируютс  на пропеллерной мешалке в течение одного часа при концентрации 0,1%. Полученна  бумажна  масса обезвоживаетс  на сетке. Сушка влажного листа осуществл етс  цилиндре буммашины при 35°С до сухости 80% без сушильного сукна. Затем бумага сушитс  при 90°С на цилиндре, снабженном сушильным сукном. Полученна  бумага имеет разрывную длину 3400-4200 м, число двойных перегибов - 600.Polyvinyl alcohol fibers with a metric number of 6000, which are dissolved in water at 60 ° C, are cut to a length of 1-3 mm, suspended on a propeller stirrer for one hour at a concentration of 0.1%. The resulting paper pulp is dewatered on a grid. Drying of the wet sheet is carried out with a cylinder of a paper machine at 35 ° C to a dryness of 80% without drying cloth. The paper is then dried at 90 ° C on a cylinder provided with a drying cloth. The resulting paper has a breaking length of 3400-4200 m, the number of double kinks is 600.

Предмет изобретени Subject invention

Способ изготовлени  синтетической бумаги, из водорастворимых поливинилспиртовых волокон , включающий диспергирование волокон в воде, ОТЛИ1В полотна и сушку, отличающийс  тем, что, с целью придани  бумаге повышенной механической .прочности, бумажное полотно предварительно высущивают до 15-20%, содержани  воды при 30-40°С, затем сушку производ т при 80-100°С до конечной сухости .A method of making synthetic paper, from water-soluble polyvinyl alcohol fibers, including dispersing fibers in water, UTLY1B cloths and drying, characterized in that, in order to impart increased mechanical strength to paper, the paper web is pre-dried to 15-20% water content at 30 40 ° C, then drying is performed at 80-100 ° C until final dryness.
